The circumference of the circle shown below is 42 centimeters. which expression gives the length in centimeters of ?

To evaluate for the length of the diameter we proceed as follows: circumference is give byc=πdbutc=42 cmhence plugging in the values and solving for d we get: 42=πd=d=42/π=13.37 cmhence the diameter is 13..37 cm

It will be the number of the circle divided by 360 multiplied by 42 pie
